Abstract

PURPOSE:To efficiently execute translation processing and to reduce work for correcting a translated sentence by post edition by inserting a specific character string for specifying a reference method for a translation dictionary into an input sentence so as to optionally specify and change the reference method of the translation dictionary. CONSTITUTION:The machine translator is provided with plural translation dictionaries 1, a dictionary reference table 2 including dictionary reference types indicating the reference methods of the translation dictionaries 1 at the time of analyzing morphems and specific character strings corresponding to the dictionary reference types as pairs and a morphem analyzing means 4 for changing a dictionary reference type into the one corresponding to a specific character string when a character string coincident with the specific character string appears, and at the time of retrieving the dictionary, retrieving the dictionary correspondingly to the dictionary reference type. When the specific character string specifying the reference method of the translation dictionary is inserted into an input sentence, the reference method of the translation dictionary at the time of analyzing the morphems is changed in accordance with the specific character string. Thus, translation processing can be efficiently executed.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to a machine translation device having a plurality of translation dictionaries.

(b) Conventional technology When performing translation processing on a machine translation device that has multiple translation dictionaries, conventionally, the method of referring to the translation dictionaries is predetermined, or the method of referring to the translation dictionaries is selected before performing the translation processing. Then I started the translation process.

Multiple translation dictionaries used for this reference method include:
Basic dictionaries, user dictionaries, specialized dictionaries, etc. prepared in advance on the system side can be considered, but for example, when translating multiple sentences at once, conventionally only the basic dictionary is referred to for a certain sentence. However, for other sentences, it was not possible to refer to the dictionary in the order of specialty, user, and basic.

Also, when there are multiple words with the same headword in one sentence, it is not possible to obtain the translation from the basic dictionary for one word and the translation from the specialized dictionary for another word.
After the translation process was completed, it was necessary to correct the translated word to the desired one.

(c) Problems to be Solved by the Invention The present invention has been made to eliminate the above-mentioned drawbacks, and provides a machine translation device that can freely change the reference method of a translation dictionary during translation. It is something.

(d) Means for Solving the Problems The machine translation device of the present invention is a machine translation device that performs translation processing on an input sentence, and includes a plurality of translation dictionaries and a method for referring to the translation dictionaries during morphological analysis. If a dictionary reference table is a pair of a dictionary reference type indicating a dictionary reference type and a special character string corresponding to the dictionary reference type, and a character string that matches the special character string in the dictionary reference table appears, the dictionary The present invention is characterized by comprising a morphological analysis means that changes the reference type to a dictionary reference type corresponding to the special character string, and performs dictionary lookup according to the dictionary reference type at the time of dictionary lookup.

(e) Function: When a special character string instructing how to refer to a translation dictionary is inserted into an input sentence, the machine translation device of the present invention converts the text into a form according to the special character string. Translation during m-element analysis 1 The method of referring to the translation dictionary can be changed to make the translation process more efficient.

Example) Here, a case of translating Japanese into English will be described.

FIG. 1 is a schematic diagram of a Japanese-English translation device according to an embodiment of the present invention. In the figure, (1) is a translation dictionary that stores Japanese headwords and their corresponding English translations, as well as the information necessary to analyze the syntax and meaning of Japanese sentences and generate English sentences. (2 ) is a dictionary reference table in which a dictionary reference type indicating a method of referencing a translation dictionary during morphological analysis is paired with a special character string (which may be one character) corresponding to the dictionary reference type.

(3> is the original text input section that inputs Japanese sentences. (4) is during morphological analysis, and if a character string that matches a special character string in the dictionary reference table (2) appears, the dictionary reference type is selected. Change to a dictionary reference type that corresponds to special character strings, and use a translation dictionary according to the dictionary reference type when looking up a dictionary.1)
Looks up the dictionary while referring to , and divides the input sentence into word units. (5) is a translation generation unit that generates and outputs an English sentence based on the words divided in the morphological analysis unit (4>) and the translation dictionary (1). (6) outputs the translation to a display device, printer, etc. This is the translation output section.

The translation dictionary (1) further includes a basic dictionary (7), a user dictionary (8>), and a specialized dictionary (9).

FIG. 2 is a diagram showing the contents of the dictionary reference table, which is composed of pairs of dictionary reference types indicating how to refer to the translation dictionary during morphological analysis and special character strings corresponding to the dictionary reference types.

Figure 3 shows that when a character string that matches a special character string in the dictionary reference table appears in the input sentence, the dictionary reference type is changed to the dictionary reference type corresponding to the special character string, and when looking up the dictionary, the dictionary reference type is changed to the dictionary reference type corresponding to the special character string. It is a flowchart showing the operation of morphological analysis in which a dictionary is looked up in a translation dictionary (1>) according to a reference type and an input sentence is divided into word units.

The operation flow in the figure will be briefly described below.

Step A: For morphological analysis of the first sentence in the input sentence,
(Step C); otherwise, proceed to (Step B).

Step B: 1 for k (character from the beginning of the input sentence)
and set a (reference only to the basic dictionary) as the dictionary reference type X.

Step C: If Ck is a character indicating the end of one sentence or a character indicating the end of an input sentence, the process ends; otherwise, the process moves to (Step D>).

The string from step IIC is stored in the dictionary lookup table (2
), the process moves to (step E); otherwise, the process moves to (step G).

Step E: Change the dictionary reference type X to the dictionary reference type corresponding to the matched special character string.

Step F: Add the number of characters of the special character string to k and return to (Step C).

Step G: A dictionary lookup is performed for the undivided portion (the character string after Ck) in a translation dictionary according to the dictionary reference type X, and a divided word is determined.

Step H: Add the number of characters of the divided carved words to k, and return to (Step C).

Next, we will explain the operation of morphological analysis when the input sentence "I buy ◆gold◇ with money." is input. Note that ◆ and ◇ are special character strings indicating the dictionary reference types of s and d in FIG. However, the basic dictionary (7) contains the entry word ``I (translation: I)''.
``money''``buy'' i
', 'de', 'wo'.

is registered, and the user dictionary (8) has "Kin (translation i1
1: gold)" is registered.

When the translation process starts, morphological analysis of the first sentence begins (step A), so 1 is assigned to k and a (reference only to the basic dictionary) is set as the dictionary reference type X (step B).

Next, C1'I' is the special character string 1 ◇, ``◆, r mouth'', ``■, △'' in the dictionary reference table (2).

Since it does not match with any of the words "mu" (Step D), perform a dictionary lookup in the basic dictionary according to dictionary reference type a (refer only to the basic dictionary) and search for the headword 1 "I (translated word: 工)" as the divided word. (Step G). Similarly, C2' is the special character string "◇" 1 in the dictionary reference table (2).
◆"10""■"1△"1" does not match (Step D), so look up the basic dictionary and search for the headword "ha" and use it as a split word.Step G> The same goes for the rest. In this case, ``money'' becomes the dividing word.

Next, C5'◆'' matches the special character string ``◆'' in the dictionary reference table (2) (step D), so replace X with ``◆''.
(step E). Next, "C6'gold" is a special character string "◇j"◆, r mouth" in the dictionary reference Google (2)
Since it doesn't match either "■yo"△" or "mu," I first looked up the user dictionary according to dictionary reference type b (refer from user to basic), and the entry word 1kin (translation =
gO1d) Search for j. Since the word is found in the user dictionary, the entry word ``g'old'' is used as the divided word without performing a dictionary lookup in the basic dictionary (Step G).

Next, C7'◇" matches the special character string r◇" in the dictionary reference table (2) (step D), so change X to "◇
, change to the dictionary reference type a (refer only to the basic dictionary) corresponding to (step E), CB "wo" is the special character string "◇", "◆", "mouth", "■" in the dictionary reference table <2). , “
Since it does not match either △ or "mu" (Suup D)
, according to the dictionary reference type a (reference only to the basic dictionary), performs a dictionary lookup of the basic dictionary, searches for the entry word "wo", and uses it as a divided word (step G). Similarly, C9 ``buy'' is the special character string 1◇, ``◆4 口'' in the dictionary reference table (2).
Since it does not match with any of ``1■'', ``△'', and ``mu'' (step D), we perform a dictionary lookup in the basic dictionary according to the dictionary reference type a (refer only to the basic dictionary) and find the headword ``buy (translation: buy)p. Search for and use as divided words (Step G)
.

As described above, morphological analysis is performed, and the translation generation unit generates an English translation while referring to the result and the translation dictionary (1). Then, in the translation output section, for example, as shown in Fig. 4, 'I buy gold' is displayed on the display.
With m0ne3', it can be displayed as J.

(g) Effects of the Invention According to the machine translation device of the present invention, it is possible to insert a special character string that instructs how to refer to a translation dictionary into an input sentence, so the method to refer to a translation dictionary can be freely changed.
Translation processing can be performed efficiently, and the work of correcting translated words in post-editing can be reduced.
